Firstly, according to Greek mythology, Zeus killed his father to cease the cannibalism, and for that he became the ruler of all Gods and the God of sky and rain. Zeus despised liars, oathbreakers and those who show no hospitality, it is generally assumed that a couple who lived in poverty showed kindness, compassion and gave Zeus their full attention (which others did not), as Zeus disguised himself as a travelling mortal, those who did not show kindness, compassion and hospitality were punished by death. The moral of this myth is to be courteous to all, regardless of their appearance. This myth advises people that there is no reason to be despisable of others.
